Answer:
y = (-4/3)x + 4
Step-by-step explanation:
Let y = mx + b, be the equation of the line in slope intercept form where we need to find m and b.
Perpendicular to y = (3/4)x - 5, means that m = - (1 / (3/4) ) = - 4/3
So, at this point, y = (-4/3)x + b.
Crossing the x - axis at 3 means that (3, 0) is a point on the line, where we note that x=3 and y=0.
Thus, we plug in these values into the equation y = (-4/3)x + b, to get
0 = (-4/3)(3) + b
0 = -4 + b, so that
b = 4.
Hence, the answer is:
y = (-4/3)x + 4
4 year college Tuition: $28,800.00

So, no, her family did not save enough for college.
74.6786 m² is the answer.
Step-by-step explanation:
<u>Step 1</u> :
we know that the diameter (D) of the cookie = 32 ft
Converting dimensions from feet (ft) to meter (m)
1 ft = 0.3048 m
32 ft = 32 × 0.3048
= 9.7536 m
<u>Step 2</u> :
To find the surface area of the cookie we have the formula,
<u> Area (A) = π . r²</u>
Diameter (D) = 32 ft
∴ d = 2r
d/2 = r (radius)
32 ÷ 2 = r
<u> r = 16</u> 16 feet = 4.8768 m
π . r² = 3.14 × (4.8768)² = 3.14 × 23.783
= 74.6786 m²
